  • Mybatis generator(复制粘贴完成)

    命令行模式

    1、java -jar mybatis-generator-core-x.x.x.jar -configfile generatorConfig.xml

    2、Maven plugin(mybatis-generator-maven-plugin) 常用

    2.1、mvn mybatis-generator:generate

    2.2、${basedir}/src/main/resources/generatorConfig.xml 默认读取这个文件,所以新建项目的话,直接添加这个文件即可。

    3、java 程序

    4、Ant Task 少用

    generatorConfiguration

    context

    1、jdbcConnection

    2、javaModelGenerator

    3、sqlMapGenerator

    4、javaClientGenerator(注解方式/xml方式/混合方式),简单的用注解方式,用到一些例子的话用xml方式

    5、table

    生成时可以使用的插件(内置插件都在org.mybatis.generator.plugins中)

    1、FluentBuilderMethodsPlugin

    2、ToStringPlugin

    3、SerializablePlugin

    4、RowBoundsPlugin(分页有用)

    ...

    使用生成对象

    1、简单操作,直接使用生成的xxxMapper的方式

    2、复杂查询,使用生成的xxxExample对象


    说了那么多,具体操作可以直接做以下2个步骤即可。

    1、在springboot的启动类上,添加如下代码

    2、加上一个配置文件

    使用了java代码的方式进行生成代码

    @SpringBootApplication
    public class PointReportApplication implements CommandLineRunner
    {
    
        public static void main(String[] args) {
            SpringApplication.run(PointReportApplication.class, args);
        }
    
        @Override
        public void run(String... strings) throws Exception {
            generateArtifacts();
        }
    
        private void generateArtifacts() throws Exception {
            List<String> warnings = new ArrayList<>();
            ConfigurationParser cp = new ConfigurationParser(warnings);
            Configuration config = cp.parseConfiguration(
                    this.getClass().getResourceAsStream("/generatorConfig.xml"));
            DefaultShellCallback callback = new DefaultShellCallback(true);
            MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
            myBatisGenerator.generate(null);
        }
    
    }

    创建一个xml文件,文件名称为:generatorConfig.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE generatorConfiguration
            PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
            "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
    
    <generatorConfiguration>
        <context id="H2Tables" targetRuntime="MyBatis3Simple">

            <plugin type="org.mybatis.generator.plugins.SerializablePlugin" />
            <plugin type="org.mybatis.generator.plugins.RowBoundsPlugin" />
    
            <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                            connectionURL="jdbc:mysql://119.23.209.247/test?truecharacterEncoding=UTF-8"
                            userId="root"
                            password="asd222030">
            </jdbcConnection>
    
            <javaModelGenerator targetPackage="com.ky.pointreport.dto"
                                targetProject="./src/main/java">
                <property name="enableSubPackages" value="true" />
                <property name="trimStrings" value="true" />
            </javaModelGenerator>
    
            <sqlMapGenerator targetPackage="mybatis.mapper"
                             targetProject="./src/main/resources">
                <property name="enableSubPackages" value="true" />
            </sqlMapGenerator>
    
            <javaClientGenerator type="XMLMAPPER"
                                 targetPackage="com.ky.pointreport.dao"
                                 targetProject="./src/main/java">
                <property name="enableSubPackages" value="true" />
            </javaClientGenerator>
         
            <table tableName="jd_ky_consume_detail" domainObjectName="jdKyConsumeDetail" > 
                <generatedKey column="id" sqlStatement="CALL IDENTITY()" identity="true" />
            </table>
        </context>
    </generatorConfiguration>
